The Model European Union was a simulation of European institutions that employed innovative teaching techniques to educate on European policies and institutions. We realized that, no matter how much we explained these institutions to young people, experiencing them for a week had a greater impact on their lives and helped them understand, respect, and appreciate them more. The aim was to continue an activity implemented in the previous academic year with positive results, but expanding it to address two issues affecting youth: climate change and sexual exploitation. With this, we intended to open a dialogue that reflected our environmental protection values and concerns for social issues. Environmental issues affect everyone and know no borders, posing a problem that requires a European-level solution. On the other hand, prostitution is a transnational issue with diverse and contradictory responses across the European territory. The goal was to observe the conclusions the European Union could reach and what insights young participants could draw to convey to policymakers. The use of simulation greatly motivated young people to get involved and allowed participants to learn a practical understanding of the European Union's institutions. The main objectives of the project were: 1. Promote civic participation in the European Union: providing tools to understand how actions and decisions can influence the political and social environment at the European level. 2. Generate debate on the environment and the sex trade: sparking students' interest in European affairs and fostering a deeper understanding of the challenges and opportunities facing the EU. 3. Increase understanding of the internal functioning of major European institutions: through simulation, students could better understand how these institutions operate, how decisions are made, and how agreements are negotiated. 4. Strengthen democratic values and dialogue and negotiation skills (aiming to develop assertiveness), as well as foster a critical citizen attitude: the simulation provided students with the opportunity to debate diverse and inclusive topics such as sexual exploitation, offering different perspectives and essential teamwork skills. 5. Address the need to go beyond theoretical knowledge, immersing participants in practical experience and demonstrating a greater interest in these issues: we supplemented theory with a life experience. 6. Young people's contact with policymakers: students gained practical experience in international negotiation, diplomacy, and transnational collaboration – valuable skills for those pursuing careers in international, diplomatic, or foreign relations. 7. Highlight the European Union and its impact on environmental and social policy formulation. With all of this, we aimed for Dialogue with Youth , with two objectives in mind: 1) bring young people together with policymakers to inform youth policies, and 2) through simulation, provide young people with insight into decision-making processes. The project addressed both aspects in two phases. In the first part, known as the simulation, young people had the opportunity to learn the positions of experts and politicians on the issues discussed. In the second part, after gaining awareness of all facets of the problem, young people shed their simulation roles and offered their perspectives, drawing conclusions.
